DELIVERY MECHANISM FOR PAPER--BAG MACHINES.

SPECIFICATION forming part of Letters Patent No. 427,289, datedMay 6, 1890. Application filed February 4, 1890- Serial No. 339,123. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES ARKELL, of Canajoharie, in the county of Montgomery and State of New York, have invented new and useful Improvements in Delivery Mechanisms for Paper-Bag Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this specification.

My invention relates to a mechanism for perfecting the final discharge or delivery and for the reception of an accumulation of the delivered articles, adapted especially for use in connection with machines for making or finishing what are known as satchel-bottom paper bags, although my inventionvmay be applied with more or less advantage to any machine from which any sort of folded and finished paper articles that will not naturally pile up evenly upon a receiving-table are to be discharged.

As is well known to those skilled inthe art and familiar with the usual fly devices and other contrivance used for efiecting the final discharge and piling of sheets or articles of a er either from a rintin ress a a ercharged from the machine is (like a satchelfolding machine, or a bag-making machine, it has been found practically impossible to effect the storage of any considerable quantity or pile on the receiving-table of any such machine by any of the heretofore-employed delivery mechanisms, when the article disbottom paper-bag) in that condition that one end or end portion of the finished article is several times thicker than the other portion, because such article piles up so unevenly that before many of the articles shall have been amassed or accumulated the pile will tumble or go to pieces.

In discharging from a bag-making machine the satchel-bottom paper bags of the usual construction it is found that usually not more than twenty bags can be accumulated on the receiving-table before the accumulated mass will have to be removed by an attendant to avoid subsequent avalanche of the bags composing the pile, and hence it has been necessary to employ one attendant for each machine in order to have the accumulations of the finished bags removed from the receiving-tables with sufficient frequency.

I have devised and put into successful operation a novel delivery mechanism or com trivan ce by the use of which I am enabled to accumulate in a desirable condition a pile or mass of satchel-bottom paper bags aggregating about five hundred of the finished articles, whereby I am enabled to handle or remove the accumulations from four or five bag-machines running simultaneously and at the usual rate of speed with the use of only one operative or attendant for the whole series of machines. This desirable end I have attained by the use, in connection with the usual delivering-drum of the bag-machine, of a novel construction of delivery mechanism and receiving-table, which will be hereinafter more fully explained and the novel features of, which will be more particularly pointed out in the claims of this specification.

To enable those skilled in the artto make and use my invention, I will now proceed to more fully describe the same, referring by letter to the accompanying. drawings, which form part of this specification, and in which Figure 1 is a side elevation of my novel device and the delivering-roller of a satchel-bottom paper-bag making or finishing machine. Fig.

2 is a plan View of the part seen in elevation at Fig. 1. Fig. 3 is a sectional view taken in front of the transferring-wheels, as at line 1 1 in Fig. 1.

In the several figuresthe same parts Will be found designated by the same letters of reference.

In the drawings, A represents a portion of the frame-work of a bag-machine, and B the delivering roller or drum of the same. To the shaft of this roller or drmn is secured a cam a, which cam can be of any suitable construction for actuating a lever intermittingly.

O is the wheel divided into two or more sections or rims. The drawings show this wheel to be made of four rims c c c 0 (See Figs. 2 and 3.) These rims are set a short distance apart to permit the admission between them of guiding-strips, and each one is connected with the shaft or axle D by suitable spokes d d. This shaft D'has its bear-' ings in the standards E, fixed to the frame or base F.

G is a lever, of any suitable form, pivoted to one end of shaft D and having its opposite end resting on the cam a, so as to be operated thereby when the delivering-drum B is revolved.

H is a circular rack fixed to the side face of the outer rim of wheel 0, and I is a pawl pivoted to the lever G at a point opposite'the rack at the forward portion of said rim, as shown. At each revolution of the shaft b the cam a will lift the free end of the lever G,

and thereby move the end of pawl I upwardly to a short distance, and, engaging with atooth of the circular rack II, this upward movement of the lever and its pawl will give an impulse to wheel 0 and cause it to revolve a distance equal to the length of the lift of said pawl.

J J are guiding strips or skids, which are supported from any suitable panel or bench, as K. These strips or skids have their forward ends extended to near the rear side of the drum B, and their rear ends are carried rearwardly to within the openings between the rims c, c, 0 and 0 These strips or skids bridge over the opening between the drum or roller B and the wheel 0, and serve as a way over which the bags will slide rearwardly from the delivery-drum B to the transferwheel C.

L L are a second set of guiding strips or skids, which are arranged between the rims c, 0, c and c of wheel 0 and the receivingtable M, and are preferably secured to said table, as shown. These strips prevent the bags from dropping down between the wheel 0 and the table M. The table M is made with an inclined top m, and is provided atits rear and lower end with stakes or stopping-pinsn n, which stakes or pins stop the progress of movement of the bags on said table. If preferred, an upwardly-inclined board can be used in lieu of pins 71 12, when said board is extended upwardly and rearwardly. This table is removable at will, and is interch an geable with a similar table at pleasure. As fast as the bags are finished on the bag-machine and delivered from the drum B (or equivalent apron) of the machine, they will be deposited on the inclined strips J, and each succeeding bag will be made to push the preceding one in direction of arrow 2 and toward the wheel 0, when the second succeeding bag will fall with its bottom end first on the second preceding one and be made to move it and the bag below at a farther distance rearwardly, when the wheel 0 will raise the bottom end of the lower bag as it is being pushed rearwardly, and these operations being continued the bags will be progressively and successively worked rearwardly onto table M and downwardly on its inclined top until their further movement will be stopped by the pins or stakes n n, and at these stakes the machine will gradually pile up the bags one on the other in an orderly manner until they form a sufficient pile on the table to be removed. As each succeeding bag falls and laps on the preceding one, and all are together worked rearwardly to the pins 02 n, the lower or preceding bags will arrive at the said pins first, and the succeeding ones will be slid up over those below without being in the least retarded in their movement by the latter.

By increasing slightly the inclination of the skids or strips J between the drum B (or an apron) of a machine for making sheets of board or other heavy paper this mechanism can be made to operate with sheets of pasteboard, straw-board, or other heavy sheets, to effect an automatic piling of the same on the table M in larger or smaller quantities, as may be desired. In some cases, if preferable, the wheel 0 can be operated by a reciprocating pawl actuated by a lever or crank or eccentric, or it can be slowly rotated by a band from the machine which delivers the articles to this device.

Having now so fully explained my invention that those skilled in the art can carry the same into effect, in either the precise form of mechanism shown or under some modified construction thereof, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with the delivery wheel or drum of a machine from which paper bags or other paper articles are discharged, of the intermittingly revolving wheel 0, suitable carrier pieces or strips J, and the receivingtable M, the whole arranged and operating together in substantially the manner and for the purposes hereinbefore set forth.

2. The combination, with the revolving wheel 0, having two or more rims separated from each other, and the inclined table M, provided with stops n, or their described equivalent, of the skids J, located between the said rims and also between the said wheel and the delivery wheel or drum B, or its described equivalent, all substantially as and for the purposes set forth.

3. The combination, with the table M, the wheel 0, provided with a circular rack, and the lever G, provided with a pawl engaging with said rack, of a revolving cam operating upon the free end of said lever, all substantially as and for the purposes set forth.

4. The combination, with the drum B, or its described equivalent, the revolving wheel 0, the skids J, and the inclined table M, provided with skid-pieces L and pins n, of the circular rack connected with said wheel, and a lever and pawl operating in conjunction with said rack, substantially as hereinbefore set forth.

In witness whereof I have hereunto set my hand this 27th day of January, 1890.
